部署 Memcache 1 & Memcache 2 # tar xf libevent-2.0.15-stable.tar.gz # cd libevent-2.0.15-stable [iyunv@localhost libevent-2.0.15-stable]#./configure && make && make install # tar xf memcached-1.4.5.tar.gz # cd memcached-1.4.5 [iyunv@localhost memcached-1.4.5]#./configure && make && make install # ln -s /usr/local/lib/libevent-2.0.so.5 /usr/lib/libevent-2.0.so.5 [iyunv@localhost memcached-1.4.5]# memcached-h [iyunv@localhost memcached-1.4.5]# memcached-p 11211 -l 192.168.122.40 -u root -m 10 -c 10 -vvv -f 1.2 -n 60 打开监听
部署 Tomcat 1 & Tomcat 2 支持连接 Memcached # cp session/*.jar /usr/local/tomcat/lib # vim /usr/local/tomcat/conf/context.xml <ManagerclassName="de.javakaffee.web.msm.MemcachedBackupSessionManager" memcachedNodes="n1:192.168.0.115:11211,n2:192.168.0.110:11211" failoverNodes="n1" requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$" transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory" /> 注意：定义内容要写在<Context></Context>里面 [iyunv@localhost tmp]#/usr/local/tomcat/bin/shutdown.sh [iyunv@localhost tmp]# /usr/local/tomcat/bin/startup.sh
最终测试 1.访问 index.html 由 Aapche 处理, 2.访问 index.jsp 交给 Tomcat 1 与 Tomcat 2 负载处理, 3.访问 index.jsp 时在 Tomcat 1 与 Tomcat 2 之间进行切换,并且 session_id 不会变化
